Who's claiming a contribution to the atmosphere, who's vouching for it, and how fresh that vouching still is. Reward (attester tier) is a stamp — fixed, stored on the record. Freshness (time since last attested) is computed — it fades until someone re-attests.
Project names/descriptions are real (atproto.science/ecosystem) — none has actually claimed a collection. Attester handles (.test), DIDs, and every attestation below are invented placeholders for design review, not real claims.
